SNUBBING DEVICE FOR YARN-WINDIN G MACHINES.

Application filed January 27, 1921.

To all whom it may concern Be it known that we, EDWARD F. GLAZIEI: andHENRY S. BROMLEY, citizens of the United States, residing inPhiladelphia,

Pennsylvania, have invented a- Snubbing Device for Yarn-\VindmgMachines. of

which the following is a specification.

Our invention relates to yarn winding machines, the main object of theinvention being to provide a device for automatically snubbing orbreaking the strands of yarn when the spools become full or when apredetermined amount of the yarn has been wound thereon.

A further object is to provide the said device with adjustable meanswhereby the amount of yarn received by the spools before the snubbingoccurs may be accurately regulated.

in the attached drawings:

Figure 1, is a side elevation of a portion of a yarn winding machineequipped with our device;

Fig. 2, is a plan view of the portion of the winding machine shown inFig. 1;

Fig. 3, is a side elevation of the snubbing device;

Fig. 4, is a plan View of the device, and Fig. 5, is a section taken onthe line 55, Fig. 3.

In yarn winding machines, at the present time, considerable losses ofyarn are experi enced due to the inability of the operator to attendwith precision to all of the considerable number of spools under his orher supervision, there being unavoidably, unless the number of operatorsis increased beyond reason, an occasional overwinding of one or other ofthe said spools before the operator can move to break the strand beingwound thereon. The excess yarn upon the overwound spools must beremoved, and very often after removal is found Worthless for future use.At best, a considerable loss of time is unavoidable.

lVe have invented a device for automatically snubbing the yarn leads tothe various spools when a predetermined amount of the yarn has beenwound thereon, whereby the above described losses are eliminated and thenumber of attendants required for a given number of spools substantiallyreduced.

With reference to the drawings, 1 desig- Serial No. 440,377.

nates a portion of a win-ding frame, in suitable bearings on which ismounted a shaft 2 which carries a smooth-faced driving wheel 3, saidshaft 2 receiving a rotary motion from some suitable external source ofpower. Carried in a suitable carrier 4 and adapted normally to lie withitsface in frictional engagement with the face of the wheel 3, is aspool 5, upon which the yarn taken in the present instance from the yarncone 7 is to be wound, the said yarn, indicated by the reference numeral6, extending to the said spool from the said cone 7 over a guide roller8 carried upon the arms 9 extending from the frame 1. The spoolcarriers/t comprise two parallel upwardly extending arms 1 joinedtogether at their base by a lateral rod 10, which is established withinhook bearings upon the said frame 1, and a downwardly and rearwardlyextending weight arm 4' at one side thereof upon which is a suitableweight 11. The said weight tends to carr the arms 4, in which aresuitable slottet bearings 12 for the trunnions 5 of the spool 5, towardthe wheel 3 whereby the face of the said spool is held against the faceof the wheel.

Carried by a reeiprocatory bar 13 in bearings 14 upon the said frame 1,is a yarn gulde 15, said yarn guide having in the present instance avertically disposed slot through which the yarn passes, the said guidereciprocating in front of the spool 5 and carrying the yarn from side toside thereof it is wound, causing an even distribution of the yarn uponthe spool.

From the above description, the operation of the machine will beapparent. The wheel 3 revolves the spool, 5 by frictional engagementwhereby the yarn is drawn from the cone 7 onto the roller 5, the yarnguide 15 reciprocating as described to distribute the yarn over thespool. As the spool becomes full, the arms 4? are forced backwardly fromthe wheel 3. The initial position of the spool is shown bv the dot anddash lines in Fig. 1, the initial corresponding position of that portionof the yarn 6 which extends between the guide 15 and the spool beingalso indicated in dot and dash lines.

Mounted so as to lie intermediate of the yarn guide 15 and the spool 5is the snubbing device which forms the subject matter of this invention,the device consisting in the present instance of a suitable support 16secured to the frame 1 by means of a bolt 17 which extends through oneof a number of apertures 18 formed in the said support. Carried at thetop of the support 16 is a snubbing head 19 having a lateral extension19' at the top thereof which is disposed parallel to the face of thespool This extension 19' has in the present instance a triangular recess20 extending backwardly from the end edge thereof, the said recess beingsuch that a sharp point 21 is formed at the lower forward end of thesaidextension. A fiat spring suitably secured to that face of the snubbinghead 19 which lies away from the said spool is established so as tocover sulr stantially the-entirerecess 20, with the exce tion etasmallportion 23 of the area thcreoi? l' ing directly over the said point21. he clearly illustrated Figs. 3 and 5, the said spring 22 liessubstantially flush against the face of the extension 19, the lower edge2 oi the s]f1ring in the present instance lying along the beveledinclined edge 26 of the recess 20. The snubbing head is so positionedthat the extension 19 projects over the lateral path of the yarn as ittravels from side to side with the yarn guide 15, so that even tually,when the spool becomes full and the yarn has been automatically elevatedinto the position shownin full lines in Fig. 1, the said yarn will becarried into the niche 28 above the point 21 and up the inclined edge 26until it meets the edge of thespring .2, which under the frictionalaction of the yarn against the edge "thereof is pulled tightlyagainst-the edge 26, so that the yarn is pinched between the said edge26 and the spring and is snubbed or ruptured by the continued rotationof the spool 5.

The head 19 is preferably slidable vertically upon the support 16, thesaid head in the present instance being held in a recess formed by theturned-over portion 16 of the said support, and a spring 27 suitablysecured to the support is adapted to bear against the rear edge of thesaid headto retain it in a given position, the said rear edge of thehead being notched as indicated at 28,

Fio. 3, for the reception 01" the end of the i spring. An ad ustmentvertically of the said head 19 in the support is thus provided for. Afurther adjustment of the device is provided for by means ot-thevertically aranged series oi holes 18 through which the securing bolt 17extends.

The device with slight modification may be applied to any windingmachine.

We claim: 1. In a yarn winding machine, the combination of a spool,means for revolving said spool to cause a strand of yarn to be woundthereon, a reciprocatory yarn guide adapted to carry the yarn back andforth across the face or said spool to effect a desired distributionthereon, and. a ,deviceestablished in the pat-hot and actuated by theyarn as it travels with the yarn guide for grippingthe said yarn when aspecified quantity thereoi has been wound upon the spool, whereby thecontinued rotation of the spool effects snubhing of the yarn.

2. in ayarn winding machine, the combination of a spool, means forrevolving said spool to cause a strand of yarn to be wound thereon, adevice comprising a relatively immovable member and a movable elementactuated by frictional engagement with the yarn and adapted to clamp theyarn against the said immovable member, and means for guiding the yarninto engagement with said movable element when a predetermined quantityor the yarn has been wound upon the said spool.
